LumiBarTW-40-4090 Nichia H6 Series LED Module 2700K-5000K Tunable White CRI90 TriGain 953lm

LumiBarTW-40-4090 Nichia H6 Tunable White LED Module 2700-5000K CRI90, Zhaga 28 cm

The LumiBarTW-40-4090 combines tunable white light with the outstanding efficiency of the Nichia H6 series. Its 40 LEDs, in two channels of warm white 2700K and daylight 5000K, use a narrow-band red phosphor that raises color rendering to CRI90 without the efficacy loss usually associated with high-CRI LEDs: up to 953 lm per channel at 193 lm/W. This makes it ideal for energy-efficient tunable white luminaires in offices, healthcare and commercial buildings.

Designed according to the Zhaga Book 7 standard (category L28W2), the LumiBarTW-40-4090 has a 20 mm wide, 28 cm rigid board with solderless terminals and needs no additional heat sink. It is operated with a 2-channel constant current LED driver, one channel per color, and is made in Germany with a 5-year warranty.

Applications of the LumiBarTW-40-4090 LED Module

With its separately controllable channels and Zhaga-compatible format, the LumiBarTW-40-4090 is designed for the following main applications:

• Linear lighting: Mounted end to end in linear luminaires, recessed or surface-mounted profiles and pendant lights, LumiBarTW-40-4090 modules create tunable lines of light; four modules (1.12 m) fit a 1.2 m luminaire. Behind a diffuser, the short LED pitch gives a uniform line at every setting. Read more in our guides on creating lines of light with LED strips and designing efficient LED linear lamps.
• Cove lighting: Installed in ceiling or wall coves, the modules produce indirect light whose color can follow the time of day or the occasion: warm light for a relaxed atmosphere, cooler light for activity and concentration. The rigid board makes it easy to align the modules precisely along the cove. Learn how to plan it in our cove lighting guide.
• Human-centric lighting: The 2 channels are controlled separately, for example with a wireless Casambi-enabled controller, so color temperature and brightness can follow a daily program: activating light during the day and warm, dimmed light in the evening, supporting well-being and the natural circadian rhythm in offices, schools, healthcare, care homes and homes. Read more about Human Centric Lighting with adjustable intensity and color temperature and how wireless Casambi control enables human-centric lighting scenes.
• High-quality white light: The Nichia H6 LEDs combine CRI above 90 with very high efficacy, so colors look natural at every setting. Find out which color temperature suits your project in our guide Choosing the right color temperature for LED lighting.

Built Around the Zhaga Standard (Book 7)

The Zhaga Consortium is a global lighting industry association that defines interface specifications, called Books, so that LED light engines from different manufacturers can be used interchangeably in the same luminaire. Zhaga Book 7 covers linear and square LED modules for indoor lighting that are operated with a separate LED driver and are mounted in the luminaire, and replaced, by professionals. It specifies the mechanical, thermal, photometric and electrical interfaces between the LED module and the luminaire, and defines 18 module categories by their maximum outer dimensions. In 2023, Book 7 became the first Zhaga specification to be published as an IEC standard, IEC 63356-2. More information is available on the Zhaga Book 7 page.

The LumiBar is designed according to Zhaga Book 7. With its dimensions of 279.5 x 20 mm, the LumiBar fits the Book 7 category L28W2, which defines a maximum module size of 280 x 24 mm.

• For luminaire manufacturers: a luminaire body designed around the Zhaga form factor accepts standardized modules, so you can switch to newer, more efficient LED generations or a second source without redesigning the luminaire.
• For maintenance and upgrades: existing luminaires with Zhaga Book 7 modules can be serviced or upgraded with LumiBar modules, extending their service life.
• For sustainable lighting: replaceable, standardized light engines make luminaires serviceable and support the replaceability of light sources required by the EU Ecodesign Regulation (EU) 2019/2020.

Installation and Operation

• Mounting: mount the module flat on the luminaire body, ideally on a metal surface for good heat transfer; no additional heat sink is required. Do not bend the rigid circuit board and avoid mechanical stress on the components.
• Connection: the module has solderless terminals. Strip the wire insulation at the connection point and insert the wire; we recommend a conductor cross-section of 0.75 mm² (AWG 18). Observe the marking of the channels.
• LED driver: operate each channel with its own constant current LED driver channel of 340 mA, for example a 2-channel tunable white driver. Several modules can be connected in series per channel: the current stays the same and the voltages add up (14.53 V per module), so the total must lie within the output voltage range of the driver.
• Handling: observe standard ESD precautions, keep the module away from aggressive chemicals, and store and operate it at 10% to 60% relative humidity.
• Safety: the power supply must provide short-circuit, overload and overtemperature protection, and installation must comply with all applicable electrical and safety standards and should be carried out by a qualified electrician.

Why the LumiBarTW-40-4090 Outperforms Low-Cost LED Modules

• LED quality: we use only brand-name LEDs from Nichia, the Japanese LED market leader whose researchers invented the blue and white LED technology, with full manufacturer datasheets and performance tested in the lab and in real applications.
• Production quality: the modules are assembled in Germany on an ISO-certified line with high-speed automatic placement and vapor phase soldering under a protective gas atmosphere, which prevents oxidation and cold solder joints and improves the thermal connection between LED and circuit board, an important factor for LED lifetime. Laser bar codes ensure traceability.
• Realistic specifications: all values are measured at a junction temperature of 65°C, so the performance in our datasheet matches what you get in a real luminaire.
